Garanti BBVA, one of Turkey's largest private banks, met its TRY 400 billion sustainable finance target — covering the period from 2018 to 2025 — in the first half of 2025, four years ahead of its original schedule. The bank's response to this early completion has been to set a substantially larger new commitment: TRY 3.5 trillion, equivalent to approximately $104 billion, in sustainable finance to be mobilised over the period from 2018 to 2029. The revised goal is described by the bank as the highest sustainable finance commitment made by any institution in Turkey's banking sector, establishing Garanti BBVA as the country's pre-eminent actor in the field.
The pace of acceleration that enabled early target completion is striking. As of December 2024, the bank had allocated TRY 291 billion toward the original goal, with TRY 171 billion deployed in 2024 alone. The remainder of the TRY 400 billion target was met within the first half of 2025, meaning the bank increased its cumulative sustainable finance allocation by more than a third in six months. With the original target now fulfilled, approximately TRY 3.1 trillion remains to be deployed under the new commitment by 2029.
A LANDMARK IN TURKISH SUSTAINABLE FINANCE
A target of TRY 3.5 trillion places Garanti BBVA's sustainable finance ambition in a different category from its prior commitments and from those of peer Turkish institutions. The deployment covers a range of financing structures including green lending, sustainability-linked credit, renewable energy project finance, and social loans across corporate, SME, and retail customer segments. The scale of the commitment means that sustainable finance will represent a defining structural feature of Garanti BBVA's overall lending book, rather than a specialist or peripheral activity managed separately from mainstream banking operations.
Alongside the target announcement, Garanti BBVA disclosed that it had issued Turkey's first Biodiversity Blue bond, a debt instrument designed to support biodiversity preservation across the Mediterranean basin. Biodiversity bonds are a relatively recent innovation in sustainable capital markets, extending the green and blue bond framework into the specific domain of ecosystem protection. The issuance positions Garanti BBVA as a pioneer in an area that regulators, institutional investors, and development finance institutions are paying increasing attention to, particularly as awareness of biodiversity loss as a systemic financial risk has grown.
DIGITAL PLATFORM BROADENS ACCESS TO SUSTAINABILITY LOANS
In October 2025, Garanti BBVA launched a digitised sustainability loan platform, making all of its sustainability lending products accessible through both mobile and internet banking channels. The move reduces the friction associated with applying for sustainable finance products, which have historically required more complex application processes involving relationship managers and documentation requirements that can deter smaller businesses or retail customers from participating. By bringing sustainability loans into the same digital channels used for everyday banking, Garanti BBVA broadens the potential pool of borrowers who can access and benefit from its green and social finance products.
The digital platform launch reflects a deliberate convergence between two of Garanti BBVA's strategic priorities: the expansion of its sustainable finance book and the deepening of its digital banking offer. For SME customers in particular, digital access to sustainability-linked loans simplifies the process of aligning financing decisions with environmental or social objectives and reduces the administrative overhead of applying for products with specific eligibility criteria. Together, the new TRY 3.5 trillion target and the digitised lending platform signal that Garanti BBVA intends to make sustainable finance a mainstream, accessible, and high-volume segment of its business rather than a niche offering for large transactions.
